Abstract:
By means of linear theory of elastoplasticity, solutions are given for
screw and edge dislocations situated in an isotropic solid.
The force stresses, strain fields, displacements, distortions, dislocation densities
and moment stresses are determined. The force stresses, strain fields, displacements
and distortions are devoid of singularities predicted by the classical elasticity.
Using the so-called stress function method we found modified stress functions
of screw and edge dislocations.
